eBGP Lo0 reachability

I have the following topology. I have 2 OSPF area 0, once running in each AS, and the links between the AS routers are set to passive.
To achieve eBGP peerings I have placed static routes onto r1, r2, r3 which has brought the peering up with the add of multi-hop. : ) The question is, on reading online it mentions that in the CCIE lab static routes would not be perferred. Therefore what other options would I have. The only other option I can see is to extend OSPF or should I be using different routing protocols perform route redistrbution.
